Usb power adapter

Community Member


I have just got the 3rd generation pro thermostat, I am going to have the thermostat on a stand using the minI usb connection but can't find out what voltage it should be and what amps. The ones on amazon are 5v but the supply that comes from the hub would be 12v, is the USB connection just to recharge the Internal batteries or power it constantly? Needless to say I have numerous 5v chargers from phones so would one of them do?

Many than,s in advance for you help

Hi there Charlie! It should constantly power the thermostat, not only charge the battery and then disconnect it. A phone charger as the ones you have, should do just fine.

Hi Paul

That's what I thought but didn't trust myself enough and just wanted confirmation before doing it to be on  safe side.

Many thanks
